Microsoft released 16 security bulletins today as part of a massive Patch
Tuesday update.

The record-breaking update includes fixes for 49
security vulnerabilities affecting Windows, Internet Explorer, Microsoft
Office and the .NET Framework. Mixed in with
the fixes is a patch for one of the zero-day vulnerabilities
used by the Stuxnet worm. According to Symantec's Joshua Talbot, Stuxnet--which
targets industrial control systems--exploited a privilege escalation
vulnerability in the Windows kernel-mode drivers.
